Adafruit QT Py ESP32-S2 WiFi Dev Board with STEMMA QT

Introducing the QT Py ESP32-S2, the tiny powerhouse for your next IoT project! This compact board features your favorite Espressif WiFi microcontroller and is packed with all the essentials to make your projects fly. With native USB, chainable I2C ports, and plenty of Flash and RAM, this dev board is perfect for building low-power, high-performance applications.

Key Features:

• ESP32-S2 Chip: 240 MHz single-core processor with native USB support, enabling it to act as a keyboard, mouse, MIDI device, disk drive, and more.
• 4 MB Flash & 2 MB PSRAM: Plenty of memory for buffering large JSON files, handling data, and supporting your IoT projects.
• STEMMA QT Connector: The chainable I2C port makes it easy to connect SparkFun Qwiic and Seeed Grove I2C devices without soldering—just plug in a compatible cable!
• Tiny Form Factor: Same size, pinout, and shape as Seeed Xiao, with castellated pads for easy soldering directly onto a PCB.
• USB Type-C: Ideal for using with modern cables; also supports native USB features across all operating systems.
• RGB NeoPixel: Built-in NeoPixel with controllable power for low power usage, perfect for visual feedback in your projects.
• 13 GPIO Pins: Includes 11 breakout pins and 2 on the STEMMA QT connector. Supports PWM, capacitive touch, and analog input/output.
• Analog and Digital Inputs: 10 x 12-bit analog inputs, hardware UART, SPI, I2S, and capacitive touch functionality.
• Low Power Consumption: In light sleep mode it draws 2-4mA, and in deep sleep, it consumes as low as 70uA, making it ideal for battery-operated projects.
• Battery Input: Supports external batteries up to 6V, with diode protection for safe operation.
• Reset and Boot Buttons: Easy access to reset your project or enter the ROM bootloader.
• Compatibility: Works with both Arduino and CircuitPython, allowing for easy development across platforms.

The QT Py ESP32-S2 is perfect for small, battery-powered IoT devices, sensor projects, wearables, and more. It’s packed with power, memory, and connectivity while maintaining an ultra-compact form factor. Get started with your next project today!

Technical Details:

• Please note there is a hardware bug in the current revision of the PCB that causes deep sleep to draw ~6mA, if you need ultra-low deep sleep current please wait till rev C is available (it is not yet, no ETA).
